Abstract:
OBJECTIVETo explore the clinicopathological and bronchoscopic characteristics of CT-occult lung cancer.
METHODSClinical data of 11 patients who were diagnosed with CT-occult lung cancer by bronchoscopy were analyzed retrospectively.
RESULTSSeven out of eleven patients had bloody sputum. The median disease course was 3 months. Nine patients were in stage I or II, among them 5 cases underwent surgery, with a 5-year survival rate of 80.0%. The upper lobes were predilection areas, and all of the 11 patients had direct sign by bronchoscopy. The most common histopathology was squamous cell carcinoma, which had proliferative changes.
CONCLUSIONSPatients with symptoms of persistent bloody sputum should undergo a bronchoscopy to make sure whether there is an occult lung cancer or not, even if the chest CT scan is negative at first visit.
